Be it known that I, EMANUEL O. GIP ,'of Chicago, in the county of Cook and State 'of Illinois, have invented certain new and useful ,5 Improvements in Safety-Locks for Package{ Carriers, of which the following is a full, clear,

and exact description, reference being hadto the accompanying drawings, forming a part of this specification, in which corresponding letters of reference in'the different figures indicate like parts- In the use of package-carriers in which the usual detachable baskets are employed and connected to the car by means of an automatic locking device it frequently occurs, as a result of imperfect construction or vcareless usage on the part of theoperator, that'the' basketbecomes released fromthe car either when the im'pulse is given to the latter to send it over the line ordu-ring its passage, when the basket,with its load, falls to thefioor. Inasmuch as this frequentlyhappensin stores crowded with customers severe personalim jury, followed by damage-suits, often results,

to say nothing of the breakage of costly showcases and valuable goods. I o I a The object of my invention is to overcome this difticultyby providing asupplemental.

safety locking device by, which thebasket may be firmly and. positively secured to the car regardless of whether the primary lockin g device is properly engaged or not.

I do not herein confine myself to nor claim any specific form of primary locking-mechanism, inasmuch as my improved safety appliance may be satisfactorily used with any one of many well-known formsof automatic locks used for this purpose. That which I have shown and the use of which I prefer is fully described'and is also claimed in apending application filed by me on the 23d day of May, 1898, as Serial No. 681,458, and therefore I shall not attempt herein to give a full and minute description of its construction or 5 operation, as I do not deem it essential to a perfect understanding of my invention.

In the drawings, Figure l is a side View of my improved apparatus as it would appear in use in a store, showing the suspended basket disconnected and lowered from the car;

Fig. 2 is a vertical sectional view indetail. taken upon the line 2 2,1 ig, 1, as the same would; appear when the'plate is attached to thebasket by meansof the locking mechanism of the car. Fig, 3 is a plan view of a por- 't-ion of apackage-carrier embodying the features of my invention. Fig. 4 is a vertical longitudinal'sectional :view thereof. Fig. 5 is avertical sectional view taken upon the line-5 5, Fig. -1,viewed in the direction of the arrowthere shown. Fig. 6 is a likesectional View taken upon the line 6 6, Fig. 3 and Fig. 7 is a plan view in detail of the releasingstirrup and spiral locking-studs, the latter being shown in transverse section.

Referring to the drawings, or represents the body or frame of the car, which. is provided with one or more wheels 1), adapted to .run

upon the-usual tautwire or elevated way.

fA metal plate c, having a cross bar d, is attached to the upper ends of wires 6, from which the usual basket orgoods-receptacle is suspended. A-knuckle' or locking device'f (better shown in Fig. 4) is pivoted at g, between the twoparallel bars of the frame a,

of which is adapted to be engaged and held in the position'shown in Fig. 4 by means of '75 and is providedjwith detents h M, the former 1 a'tooth is upon a pivoted spring-actuated dog Ladapted to bereleased, by means of a trig-.

ger m, in the manner hereinafter stated. When in said position, the bar cl, from which the basket is suspended, is engaged and locked by means-of the detent j, thus securing the basket to the car.

' A stirrup n i s arranged transversely be- 51 v vI neath the wireway and suspended by means of chains 0 0 upon opposite sides of the way, which are in turn connected with the usual lifting-cords o 0, Figs. 1 and 2, by means of which the basket is raised and lowered. The springs o 0 inclosed within the stationary 'tubes 0 0 Figs. 1 and 2, serve to hold the stirrup it normally in the position indicated in dotted lines in Fig. 2. Notches p 13, Figs. 1 and at, are formed in the plate 0 for the reception of the chains 0 0 when the car is at the sending-station. The lifting of the stirrup serves either to release the basket or to lock the same in position, according as the knucklefis in one or another position when the stirrup is lifted. \Vhen the basket is locked to the car, as shown in Fig. 4:, the trigger is in position to be engaged by the central depression q of the stirrup.

Loosely pivoted in vertical bores form ed in the plate upon opposite sides of a central longitudinal line drawn through said plate are studs M", to the upper ends of which are rigidly attached in any Well-known way but tons s 3, having lugs it upon the bottom thereof, which are adapted to engage with shoul' (Shown ders u it, formed upon the plate a. in Figs. 5 and 6 and indicated in dotted lines in Fig. 3.) Coiled springs'u'v, one end of each of which is connected with the plate cand the other with a button 8, serve to normally hold said buttons, so that the lugs t are in contact with the shoulders u. Laterally-projecting flanges w 10, Figs. 3, 5, and 6, areformed upon the frame of the car, and when the basket is locked to the car the buttons stand in the respective positions shown in said last-named figures with respect to said flanges.

Depending from the studs Ware wide spiral .3 .9 stand in the respective positionsindi cated in dottedlines in'Fig. 3, and are thus free to clear the flanges w as the basket is raised or lowered; but as soon as the stirrup is released'said buttons resume their-respective normal positions, and, assuming the release to occur when the basket is raised toits full height, so that the plate 0 is against or near to the frame a, the buttons will be in an .engagin g position above the flangesw w,-and

thus hold the basket suspended to the car, whether the main locking 'deviceis in engagement or not. placed sufficiently high above the flanges to enable them to assume their respective normal positions when the basket is raised without being brought into actual contact with the flanges unless the'primary lock fails to said buttons, said extensions being adapted engage, thus insuring a perfectly free and unobstructed movement of said buttons and providing sufficient latitude to enable them to assume positions such as will cause a positive engagement with the flanges w in the event of the failure of the main lock to act as stated.

Inasmuch as the springs o are intended merely to rotate the studs they may be made very light, and hence the auger-shaped extensions 00 a; offer no appreciable resistance to the lifting of the stirrup.

lVhile I prefer to employ two or more but- The buttons 3 3 should be tons upon opposite sides of the car-frame, it is obvious that one may serve the purpose without departing from the principle involved, and that it may be located in any suitable position to engage the car. Moreover, it is obvious that the springs 4) may be omitted, inasmuch as the buttons 8 would be moved back and forth to the desired positions by the positive action of the parts a: and slots y.

Having thus described i my invention, I Claim@ 1. Thecombination in a device of the class described, of acar adapted to run upon a way, a detachable goods-carrying receptacle, primary and secondary automatic locks for looking the two together, one of said locks being upon the car and the other upon the suspending-plate of the goods-receptacle, and a lift ing-stirru p for raisiugand lowering the goodsreceptacle, said lifting-stirrup being adapted to engage both of said locks andto actuate the same when said stirrup is raised and lowered by the operator,

substantially as described.

2. In adevice of the class described, the

combination of a car adapted to run upon a way, a detachable goods-carrying receptacle having a plate adapted to be engaged by a primary lock, a primary automatic lock mounted upon the car, a stirrup suspended from a cord or cords for raising and lowering said'recep- :tacle and actuating said primary lock, one or more buttons pivotally mounted upon said plate 'adaptedto assume engaging positions withrelat-ion' to the frame of said car when said plate is lifted into contact with the latter, and a depending auger-shaped extension connected with each of said ,buttous,'said extensions being adapted to be engaged by slots in saidstirrup and to' be actuated thereby, substantially as described.

' 3. In a device of the classdescribed, the combination of a car, a detachable goods-carrying receptacle, having a plateadaptedtoy be engaged by a primary lock, a primary au- [tomaticlock mounted upon th'ecar, astirr'up suspended from a cord or cords forraising and lowering said receptacle and actuating said .primarylock, one or more buttons pivotallymounted upon said plateadapted to assume engaging positions with relation to theframe of said car whensaid plate is lifted into contact with the latter, a depending augershaped extension connected with each of ing Witnesses, this 28th day of Febru a y, 1899- EMANUEL C.
